gnssrefl.quickplt module

gnssrefl.quickplt.main()

quick file plotting using matplotlib

A png file is saved as temp.png or to your preferred filename if outfile is given. In either case, it goes to REFL_CODE/Files

Allows you to set x and y-axis limits with a title and various axes labels

a different symbol can also be set

Someone could easily update this to include different filetypes (e.g. jpeg)

Examples

quickplt txtfile 1 16

would plot column 1 on the x-axis and column 16 on the y-axis

quickplt txtfile 1 16 -xlabel Time

would plot column 1 on the x-axis and column 16 on the y-axis and add Time on the x-axis label

quickplt txtfile 1 16 -xlabel “Time (sec)”

would plot column 1 on the x-axis and column 16 on the y-axis and add Time (sec) on the x-axis label, but need quote marks since you have spaces in the x-axis labe.

quickplt txtfile 1 16 -reverse T

would plot column 1 on the x-axis and column 16 on the y-axis it would reverse the y-axis parameter as you might want if you are ploting RH but want it to have the same sense as a tide gauge.

quickplt txtfile 1 16 -ylimits 0 2

would restrict y-axis to be between 0 and 2

quickplt txtfile 1 16 -outfile myfile.png

would save png file to $REFL_CODE/Files/myfile.png

Parameters:

  • filename (str) – name of file to be plotted

  • xcol (str) – column number in the file for the x-axis parameter

  • ycol (str) – column number in the file for the y-axis parameter

  • mjd (str) – T or True, code will convert MJD to datetime, optional

  • xlabel (str, optional) – label for x-axis

  • ylabel (str) – label for y-axis

  • symbol (str, optional) – prescibe the marker used in the plot

  • reverse (str, optional) – T or True, to reverse y-axis limits

  • title (str, optional) – title for plot

  • outfile (str, optional) – name of png file to store plot

  • ylimits (float, optional) – pair of yaxis limits

  • xlimits (float, optional) – pair of xaxis limits

  • freq (integer, optional) – use column 11 to find (and extract) a single frequency
